Zheng Bin Nov. 19, 2019, 6:14 a.m. UTC 
Fixes gcc '-Wunused-but-set-variable' warning:

arch/powerpc/perf/imc-pmu.c: In function trace_imc_event_init:
arch/powerpc/perf/imc-pmu.c:1292:22: warning: variable target set but not used [-Wunused-but-set-variable]

It is introduced by commit 012ae244845f ("powerpc/perf:
Trace imc PMU functions"), but never used, so remove it.
